چکیده
In the present work, ZnO/Bi(2)O(3) composite has been successfully synthesized using the precipitation method. The obtained sample was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and emission scanning electron microscopy (FE-SEM). The FE-SEM micrograph demonstrated that the particle size of the surface of nanocomposite was about 43 nm. The photocatalytic performance of ZnO/Bi(2)O(3) composite was evaluated by decolorization of methylene blue and congo red dye solutions under UV-Vis and visible irradiation. It was found that about 95% of the congored solution was decolored over the nanocomposite after 60 min under visible light. Also, the reusability of prepared nanocomposite was investigated through successive 4 cycles of experiments. Therefore, the synthesized ZnO/Bi(2)O(3) nanocomposite is a suitable photocatalyst to use under the visible light.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
